- TP's zoom utility
- ------------------------------------------------------------------------
-
- Most of the utility's operations are fairly straight forward. The only
- point that may not be so obvious is the format of the file that is
- requested then you press "get start/end corners". Lets say you want
- to zoom into a par file entry like:
-
- 003 { ; sodium
- reset type=mandel
- corners=-0.177579146/-0.177506542/-0.662062708/-0.662008284 maxiter=1024
- inside=0 logmap=yes
- colors=000wZI<27>vNs<11>GiR<48>H8NH7NH6NH6NG5OG5O<58>91p91pA3o<32>Xtm<38>c9E\
- c8Dc9D<4>dBFdBFeDF<7>rV9sX9uZ8wa7w`8w`9<4>wZG
- }
-
- just edit out the corners parameters into a file :
-
- -0.177579146 -0.177506542 -0.662062708 -0.662008284
-
- now load it with "get start/end corners". You may enter all those numbers
- manually by using the "edit" buttons.
-
- Since the number of iterations is more needed the deeper you zoom you may
- enter a start iteration and an end iteration. The number of iterations
- is steadily increasing along with the zoom.
-
- Now for the amazing part! enter a value in rotations. It specifies the
- number of 360 degrees rotation the image will be rotated when it is zoomed in.
-
- Even more amazing: You may edit the rotation with a spline function.
- The rotation for each frame will be sampled from this curve.
-
- As for the zooming style you may use linear zoom or one of the 1/n type zooms.
- The linear zoom is only useful for "not so very deep" zooms. The 1/n zooms can
- zoom in to any depth you like (and doing it in a resonable manner). The 1/2
- zoom splits the remainding distance from current image to the end by two and
- zooms in by that amount repeatedly. The others works in the same way but will
- use more frames to get to the end in a smooth manner. (could probably
- call it gamma zoom)
-
- Happy zooming!
